Definitions
- This invention relates to a spinal implant for placement between two opposing vertebral bodies during a fusion procedure. Description of the Related Technology
- interbody devices have been used or proposed for use in vertebral fusion procedures. These are commonly referred to as "cages” and may comprise rings, dowels, fenestrated and/or threaded boxes or cylinders that are placed between the vertebra being fused. Different styles are made from a variety of different materials including titanium, stainless steel, or carbon fiber. Dowels and rings are sometimes constructed of allograft bone. In most cases, the cage is installed into a distracted disk space following disk removal, and cancellous bone chips are implanted in and around the cage between the vertebral bodies. If the procedure is successful, bone tissue permeates the disk space through and around the cage, and a solid bony fusion is formed which rigidly couples the two vertebra.
- the invention comprises a spinal implant configured for placement between vertebral bodies comprising a housing and one or more spikes coupled to the housing and configured to couple the housing to the vertebral bodies, wherein at least one of the spikes comprises at least one laterally extending projection for engaging the bone.
- the laterally extending projection forms a barb.
- the invention comprise a spinal implant, comprising: a housing defining at least first and second pairs of holes, wherein the first pair of holes are formed on first and second surfaces of the housing, respectively, the second surface opposing to the first surface, and wherein the second pair of holes are formed on the first and second surfaces, respectively.
- the implant also comprises at least first and second pairs of spikes, the first pair of spikes opposing to each other and the second pair of spikes opposing to each other, each spike having a base portion and a top portion, wherein each spike is configured to reside within the housing in a retracted mode and the top portions of each spike are configured to protrude from the housing via the first and second pairs of holes, respectively, in an extended mode, and wherein each top portion is configured to be inserted into a vertebral body.
- At least one driver comprising at least two wedge structures mounted to an extended shaft and configured such that a first one of the wedge structures contacts the base portions of the first pair of spikes, and a second one of the wedge structures contacts the base portions of the second pair of spikes so as to transfer each spike from the retracted mode into the extended mode.
- at least one of the spikes may comprise at least one projection on its top portion, and the projection may be barbed.
- a spinal implant comprises certain gear train driven spikes.
- a gear train comprising at least a worm gear is coupled to the spike and is configured to transfer the spike from the retracted mode into the extended mode.
- a gear train comprising at least a pinion gear is coupled to the spike and configured to transfer the spike from the retracted mode into the extended mode.
- a method of fixing an implant between vertebral bodies comprises inserting the implant between the vertebral bodies, extending spikes coupled to a body of the implant into the vertebral bodies, and using the spikes to pull the vertebral bodies toward the implant body.

- FIGS 12A through 12C illustrate an interbody implant device having a rack and pinion spike driver.
- FIG. 1 illustrates an interbody implant device 10 in use.
- the interbody implant device is inserted between vertebral bodies 14, 15 following removal of the spinal disk.
- Figure 1 illustrates an anterior approach, but it will be appreciated that posterior insertion methods can be used as well with all invention embodiments described herein, and may in fact be preferable in some cases.
- the device 10 includes a plurality of spikes 12. The spikes
- the retracted mode represents a state of the interbody device
- the extended mode represents a state of the interbody device 10 where the top portions of the spikes 12 are exposed to the outside of the device 10 as exemplified in the left hand side of Figure 1.
- a few devices with expanding spikes such as are illustrated in Figure 1 have previously been proposed. These include the devices described in U.S. Patent No. 6,102,950 to Vaccaro and U.S. Patent No. 5,800,547 to Schafer et al. However, as will be described further below, insufficient attention has been paid to the design of the spikes themselves and also to their method of extension.
- the interbody device 10 can be manufactured in a mechanically compressible and expandable manner, in addition to having extendable spikes, allowing it to be placed through a small opening in its compressed state, and once inside the disk space the device 10 can expand in a horizontal direction and also vertically.
- the expansion mechanism may be a sliding mechanism that can be engaged by using a screw driver to turn and expand the device 10 horizontally. Another set of screws may then be used to turn and increase the vertical height of the device 10 and allow the teeth, anchor, or bolt to clamp and fix the interbody device 10. Additional filling of the device 10 with bone or BMP sponges or DBP sponges, etc., can be done after the device 10 is engaged and expanded to the desired height.
- the projections or spikes 12 of the interbody device 10 which extend into the vertebral bodies 14 and 15, can come in many forms.
- these projections 12 can come out as fish hooks or anchors which can then penetrate into the end plate to provide stable fixation and compression of the interbody device 10. This will allow an osteo integration with minimal dissection, minimal risk to the nerve root, minimal risk to the thecal sac, minimal bleeding, minimal scar tissue and facilitate shorter hospital stay.
- the interbody device 10 can be made of several materials that are already known in the art of spinal surgery.
- the device 100 can utilize material, such as stainless steel, titanium, PGA, PLA, PLLA, tantalum, PMMA, bone, PEEK, or other materials well l ⁇ iown and accepted, but not limited to the aforementioned.
- material such as stainless steel, titanium, PGA, PLA, PLLA, tantalum, PMMA, bone, PEEK, or other materials well l ⁇ iown and accepted, but not limited to the aforementioned.
- the interbody device 10 provides not only a means for a minimal invasive surgery, expansion within the disk space, both horizontally and vertically, stability within the disk space, easy retrieval of the device 10 in the event of infection or improper placement, but most importantly it allows for platform technology to be utilized for the first time in the disk space without any additional fixation.
- These end plate projections that penetrate the upper and lower cartilaginous end plates are uniquely designed and encompasses any device or method whereby the interbody device 10 can be anchored and compressed within the disk space.
- the geometry of the device 10 may be somewhat trapezoidal or rectangular, but is not limited to these geometric shapes. Cylindrically shaped devices could also be anchored in such a fashion. Referring to drawings, different embodiments will be discussed below in more detail. 2.
- Spike Design Figure 2 illustrates a tip design for cage spikes in accordance with one embodiment of the invention.
- the spikes include at least one projection 18a, 18b, 18c that extends outward from the base diameter of the main spike shaft 22.
- a plurality of conical projections are provided such that the spike tip forms a Christmas tree type configuration.
- the projections may increase in diameter toward the bottom of the shaft 22, or they may stay the same. It is also advantageous if the bottom surface of the projection slopes upward from the bottom edge or tip of the projection. In this way, the projections can form one or more downwardly projecting barbs. These can engage the vertebral bone like a fish-hook, for example.
- the bone tissue will tend to enclose and surround the projections, pulling the vertebral bodies toward the implant, and resisting relative motion between the implant and the vertebral bodies. Furthermore, the normal load on the spine will tend to implant the spikes deeper into the bone, which will not be completely relaxed upon reduction of loading because of the projections.
- the spike design leads to progressive enhancement of the attachment between the device 10 and the vertebral bodies 14, 15. This significantly improves fixation, inhibits device migration, and enhances the success of the fusion.
- Figures 3A through 3D illustrate an interbody implant device having a sliding wedge driver according to one embodiment of the invention.
- This device comprises a housing 40, a driver 45, and spikes 41-44.
- Figures 3B and 3D illustrate an extended mode where the spikes 41-44 are extended from the housing 40.
- Figures 3 A and 3C illustrate a retracted mode where the spikes 41-
- the spikes 41-44 are captured in holes in the housing 40.
- the driver 45 has a tapered tip which engages the heads of the spikes. To install the spikes, the driver 45 is forced into the housing 40, and the tapered surface of the driver tip forces the spikes outward.
- the driver is preferably tapped into the housing with a hammer or mallet without the need for any rotating or threaded engagement with the housing. During surgery, it has been found that such non-rotating, non-threaded methods of engagement are often easier to perform than thread based, rotating engagement designs, and this is one advantage of the system llustrated in Figure 3.
- Figure 4 shows another embodiment of a non-rotating driven wedge design with two wedge portions 48, 50 on the driver 52.
- the front wedge 48 is used to engage the front spikes 41, 43 and the rear wedge 50 is used to engage the rear spikes 42, 44.
- Wedge position on the driver 52 can be configured such that all four spikes are forced outward at the same time, or, for example, the front two spikes could be driven in before the rear wedge 50 contacts and engages the rear spikes. 4. Threaded Rotating Wedge Drivers
- Figure 5 illustrates an interbody implant device having two wedge structures, moving in the same direction, according to another embodiment of the invention.
- the device of Figure 3 comprises a housing 30, a driver 31, two wedges 32 and 33, and four spikes 38.
- a cap 36 is placed on one side of the housing 30 to close the side of the housing 30 in this embodiment.
- Figure 5 only shows a retracted mode of the device.
- the extending operation of the spikes 38 by the wedges 32 and 33 is substantially the same as that of Figures 3 and 4, except the driver 31 is externally threaded, and rotates within an internally threaded channel 37 in the housing 30.
- the driver 31 is inserted into the housing 30 such that the rotation of the driver 31 forces the wedges to move to the right by rotating the driver 31. hi order to transfer the spikes 38 from the retracted mode to the extended mode, the driver
- each wedge 32 and 33 rotates, moves to the right in Figure 5 and pushes against the base portions of each spike 38 until the top portions of each spike
- each spike 38 protrude from the housing 30. Again, two opposing vertebral bodies are coupled to each other via the protruded top portions of each spike 38.
- driver 45, 52, or 31 is removable after the spikes are set into the vertebral bodies. This leaves room inside the cage housing for the introduction of cancellous bone for fusion.
- the embodiment of Figure 5 also illustrates the use of compression springs 34 which can be provided to produce a pulling force on the vertebral bodies toward the cage housing. These may be provided in any of the cage embodiments described herein, and are especially useful when used in conjunction with the barbed spike design illustrated in Figure 2. If the springs are strong enough, they can be used to retract the spikes if the device needs removal. In these embodiments, either the driver remains in the implant, or another latch which maintains the spikes in an extended position is provided.
- Figure 6A through 6F illustrate an interbody implant device having two wedge structures, moving in opposite directions, according to one embodiment of the invention.
- the device of Figure 6 comprises a housing 60, a rotating shaft 62, wedges 64 and 66, and spikes 67-70.
- Figure 6A illustrates a cross sectional view of the implant device.
- Figures 6E and 6F illustrate an extended mode where the spikes 67-70 are extended from the housing 60.
- Figures 6A and 6D illustrate a retracted mode where the spikes 67-70 reside within the housing 60.
- the spikes are located inside the housing.
- Each spike comprises a base portion and a top portion.
- the spikes 67-70 are biased inward toward the center of the housing by a spring 72 that has a flexing central convexly bowed region that is pressed against the inside of the housing.
- the ends of the spring are coupled to a respective spike base such that the central bowed portion tends to pull the spikes inward.
- a perspective view of a suitable spring is shown in Figure 6B.
- the shaft 62 is coupled to the wedges 64 and 66.
- the shaft 62 comprises a threaded portion 74 and a head portion 76.
- the front wedge 64 has a throughhole and the rear wedge 66 has an internally threaded portion therein.
- the shaft is inserted into the throughhole of the wedge 64 until the wedge 64 reaches the head portion 76 as shown in Figure 6A.
- the threaded portion 74 of the shaft is adapted to be inserted into and engaged with the threaded portion of the rear wedge 66.
- the extended mode will be explained. As shown in these Figures, in the extended mode, the top portions of the spikes 67-70 protrude from the housing 60 via openings 80.
- the shaft is rotated, for example, clockwise, such that each wedge 64 and 66 pushes against the base portions of each spike until the top portions of each spike protrude from the housing 60 via the openings 80 respectively.
- the threaded portion 74 of the shaft rotates clockwise in the inside of the wedge 66. Since the shaft motion to the right in Figure 6A is limited by the front wedge 64, the wedge 66 moves in the left direction along the threaded portion 74 of the shaft. The wedge 64 also moves in the right direction, clamping the spike bases between the tapered surfaces of the wedges.
- each of the wedges 64,66 moves in the right and left directions, respectively, and pushes against the base portions of each spike until the top portions of each spike are exposed to the outside of the housing 60 via the holes 80.
- FIG. 7A through 7C illustrate an interbody implant device having a threaded screw structure according to another embodiment of the invention.
- the device of Figure 7 comprises upper and lower housing halves 82, 84, a pair of threaded wedge drivers 86 and two pairs of spikes 88. Each pair of spikes 88 are coupled to a hair pin spring 90 (see also Figure 7C) as shown in Figure 7A.
- the upper housing half 82 and lower housing half 84 are connected to each other via rivets 92 to form a complete housing.
- This overall design may be advantageous in some cases because the housing forms a horseshoe shape with an open central region that provides space for placement of cancellous bone chips for vertebral fusing.
- FIG 7A illustrates an exploded view of the implant device.
- Figure 7B illustrates a cross sectional view of the device in a retracted mode where the spikes 88 reside within the housing.
- each driver 86 is turned, for example, clockwise and moves inward via the tlireaded portions of the drivers 86 into threaded openings in the housing such that each of the drivers 86 pushes against the base portions of each spike 88 until the top portions of each spike protrude from the case.
- a sliding driver design such as the one illustrated in Figure 3 could also be used.
- FIGS. 8A through 8C illustrate an interbody implant device having a cam shaft structure according to another embodiment of the invention.
- the device of Figure 8 comprises a housing 90, a cam shaft 92 and spikes 94.
- Figure 8A illustrates an exploded view of the implant device.
- Figure 8B illustrates a retracted mode where the spikes 94 reside within the housing 90.
- each pair of spikes is coupled to springs 96 similar to the embodiment of Figure 6.
- a cap 98 is placed on one side of the housing to close the housing.
- the cam shaft 610 has two orientations corresponding to whether the spikes 94 are in the extended mode or in the retracted mode as shown in Figure 8C.
- the cam shaft 92 is located between the base portions of the spikes in the both of the extended and retracted modes. In the embodiment of Figure 8, turning the cam shaft 92 about 90° either clockwise or counterclockwise can transfer the spikes 94 from the retracted mode to the extended mode, and vice versa.
- Figures 9A through 9C illustrates an interbody implant device having a gear assembly structure according to one embodiment of the invention.
- the device of Figure 9 comprises a housing 102 similar to that described above with reference to Figure 7. However, instead of a moving wedge type driver for the spikes, a gear train is utilized. In this embodiment, a worm gear system is used.
- a worm gear 104 rotates along a horizontal axis and meshes with a second worm gear 106 that rotates along a vertical axis.
- Spur gears 108, 110 are provided, attached above and below the vertical rotating worm gear 106.
- a hex driver may be used to turn the horizontal worm gear 104.
- This gear assembly which is engaged with the spikes 112 that are in this embodiment provided with geared heads to engage the spur gears 108, 110 such that the spikes rotate in response to worm gear train rotation.
- the top portion of the spikes are externally threaded and engage internally threaded openings in the housing. Spike rotation then causes the spikes to move outward into the extended position.
- Figure 10 illustrates a second worm gear train embodiment which uses a jackscrew drive to extend the spikes.
- the device of Figure 10 comprises a housing 118, a worm gear 120 rotating on a horizontal axis, and internally threaded worm gear nuts 122, 124 rotating on vertical axes.
- This embodiment also includes externally threaded spikes 126 positioned inside the worm gear nuts 122, 124.
- the worm gear 120 is engaged with both of the worm gear nuts 122 and 124 such that the rotation of the worm gear 120 forces the worm gears 122 and 124 to rotate at the same time but in opposite directions.
- the spikes are prevented from rotating by being made in a hex shape and residing in mating hex shaped openings 130 in the housing 118. Because the spikes are held rotationally fixed as the worm gear nuts turn, the threaded coupling between the worm gear nuts and the spikes pushes the spikes out of the housing as the worm gear nuts rotate.
- the worm gear nut 122 is configured such that its rotation moves the spike in an upper direction as shown in Figure 10.
- the worm gear nut 124 is configured such that its rotation moves the spike in a lower direction as shown in Figure 10.
- Figure 11 is a similar embodiment as Figure 10, except the jackscrew is co-linear, with two opposed spikes residing inside one worm gear nut 134.
- the threads on opposite spikes are configured oppositely, such as right hand threads on the bottom spike and left hand threads on top spike so that the single worm gear nut rotation forces the spikes to move in opposite directions.
- FIG 12A through 12C illustrate an interbody implant device having a rack and pinion structure according to another embodiment of the invention.
- the device of Figure 12 comprises a housing 138, a pinion gear 140 and spikes with racks 142.
- Each of the spikes 142 has a rack which is configured to be engaged with the pinion gear 140.
- the pinion gear 140 is engaged with the rack spikes 142 and by its rotation configured to move the spikes linearly, for example, upward or downward as shown in Figure 12B.
- the pinion gear 140 is coupled to two pairs of rack spikes 142 as shown in Figures 11A and 11B. Each pair of spikes moves in opposite directions, for example, upward and downward, respectively, by the rotation of the pinion gear 140.
- the pinion gear 140 is coupled to more than two pairs of rack spikes and configured to move all of the rack spikes linearly.
